To altwhom it mayconcern: ABe itkno-wn thatI, Jnrrns H. LEWIS, of Detroit, fin. fthe county of Wayneand State of Michigan, have invented an Improvement in Combined RevolvingRake and Reel for Reapin g-Machines, of which the following isa specification:A The nature of this invention relatesto kcertain new and Vuseful-improvements in the construction' of combined rakes and reels to be attached` to reapingfmachines, bymeans of which, after a 'sufficient amount of grain has beencutto form a sheaf, and is lying on thel rake-table, the` same can be raked to therear thereof Vand depositedonV the ground, ready for binding, atthe willv ofthe operator. The invention Y consists, rst, in the`v combinationofcurved arms on' the reel-head, projecting outwardly from .the'center of thesame, with heads, sliding uponfsuch arms, and carrying thereellarms, and a cam-plate on the standard having a groove offsuch construction that the reel-arms can be operated to perform the, functions of a reel or a rake, or both, as desired; second,`in the peculiar construction of the cam-plate, provided with a pivoted guide-plate and a slidingguide-plate retracted by a lever, for controlling the movements of the reel-arms; and, further, in the combination of the parts for causing the reel-arms to be presented to the rake-table parallel to the cutter-bar, and retaining itin such position until compelled to make the rake or sweeping movement, all as fully hereinafter explained.

Figure l is a perspective view of my irnproved combined rake and reel. Fig. 2 is a side elevation of the same. Fig. 3 is a detached perspective of one of the rake-arms and its attachments. Fig. Avis a side elevation of parts shown in Fig. 3. Fig. 5 is a section on the line'w w in Fig, 7. Fig. 6 is a section on the line y y in Fig. S. Fig. 7 is a section on the line z z in Fig. 2. Fig. Sis a similar view, but showing the position of adjustable segments to compel the rake movement of the arms. Fig. 9 is a front elevation of one rake or reel arm with its attachments and segment of the reel-head, showing position of parts while performing the functions of a reel. Fig. 10 is a similar view, showing position of parts Fig. l1 is a to perform functions of a rake.

dated May 14, 1878; application led similar view', showing position of parts, as at the completion of the rake-stroke. Fig. 12 is arms andtheir attachments removed. In. the accompanying drawings, A repre= sents the rake-table of areapingmachine, from which risesl the standard A', its position being varied according to the style of reaperto which my device is to be` attached. In the. head of this standard A' is placeda bearing, a, -for the shaft B, which carries on its rear end a chain-wheel, B', or other suitable devices, by means of which a rotating motion can be im.- parted to the shaftand its"connections, here# inafter named.

C is a cam-plate, secured to theface of the standard A',fand hasfo'rmed in its face the circular-channel b andthe cam-channel b'. At the point of juncturebetw'een these channels, at'thetop of the cam-p1ate,is pivoted, at c, an adjustingsegmental guide, G1, 'while'at the bottom of the circular channelb, and at the point'of its juncture with the cam-channel b', and to complete the circular channel, I place anadjustable segmental plate, G2, which has a rearwardly-projecting arm or rod, d,which passes through the standard A', its rear end being secured to one end of the lever D, which is pivoted to the rear side of the standard A', as shown. A spring should be adjusted about the arm of the segmental-plate O2, or upon the lever D, to compel said plate C2 to remain in the extended position shown in Figs. 5 and oint. p Rigidly secured to the shaft B, in front of the cam-channel plate, is a reel-head, E, from the hub E1 of which extend the radial arms E2 and the quadrant-arms E3. On the quadrant-arms E3, I place sliding boxes F, to the rear faces of which I pivot friction-rollersj', which travel in the channels in the cam-plate, as hereinbefore described. These slidingboxes have rigidly secured to them arms F', the outer ends of which are pivoted to the bolts g, which pass through the radial arms E2 and into the ends of the brackets G, which are secured to the reel-head, as shown; also, pivoted upon these bolts g are the forked bell-crank levers G', in the forks of which are secured suitable springs h, for the purpose of keeping the bellavrear elevation ofthe reel-head, with the rake n 7, completing the circular channel b at that cranks and rake-arms in their proper relative T positions, as, were it not for these springs, the

arms and bell-cranks would fall over in the rotation of the device. A forwardly-projecting stud or arm, l, in each of the bell-cranks prevents the arms from moving back upon meeting any resistance from the grain upon which it is operating. One of the arms of these bell-cranks is connected, by means of rods i, with the rake or reel arms H, one end of each of which is pivoted in the sliding boxes F, while to the opposite ends are secured the rake-heads H', as in the usual manner.

The operation of this device is as follows: When it is desired to use this attachment as a reel only, the parts retain their several positions, as is shown in Fig. l, rotating in a circle, `the yfriction-wheels f traveling in the circular channel b of the cam-plate, the rakeheads compelling the grain, as cut, to lie upon the table A. When a sufficient amount of grain has been cut to make a gavel, and it is desired to rake the'same therefrom', the operator, by means of the lever D, withdraws the segmental plate G2, thus opening communication between the two channels of the camplate. As, in the rotation of the device, one of the friction-wheels f comes lto this opening, it runs into the channel b', following its course. This causes its sliding block F to slide down upon the quadrant-arm E3, carrying with it its respective rake-arm, and causes the bell-crank lever G to partially rotate upon its pivot until the arm k thereof comes in Contact with the projecting end of the shaft B. At this point therod i compels the reel-arm H to partially rotate in the sliding box, and assume the position shown in Fig. 10. The bell-crank is held in contact with the shaft until the rake-arm H is caused to assume y a nearly horizontal position by means of the roller f traveling in the channel b', and as the parts travel back toward the center, the arm H draws upon the rod t' and compels the bell-crank to assume its original position.v

I fhave shown in '.my drawings and described in my specification the employment of a bell-crank lever for producing or compelling certain actions on the part of the reel-arms; but I do not wish to confine myself thereto, as it is obvious that the same results may be produced by the employment of a single arm or lever at that point, the end of which shall come in contact with a suitable stop, either on the reel-head or standard, at the proper point to produce the desired action of parts. l

What I claim as my invention is l. In a combined rake and reel attachment for reapers, the combination, with the reelhead E, having curved arms projecting outwardly from its center, of the heads'F, sliding` on such arms, and carrying the reel-arms,an`d the cam-groove on the standard, substantially'` asand for the purpose set forth. 2. The cam-plate C, for the purposev set forth, having circular groove b, cam-groove b', pivted plate C1, and sliding plate C?, moved by a lever, substantially as described and shown. v

3. In a combined rake and reel attachment 'for reapers, the reel-arm H, sliding 'from the A center of the reel-head in performing the functions of a rake, substantially as described, in combination with the arm F', lever G', rodi, and spring h, for the purpose of causing said arm H to be presented to the rake-table parallel to the cutter-bar, and retaining it in such position until compelled to make the rake `or sweeping movement, substantially as set'forth and shown.
